Definition
A turbine engine starter that uses the energy released by burning a fuel-and-air mixture inside the starter unit to drive a turbine wheel, which in turn rotates the engine for starting. The starter has its own combustion chamber, igniter, and small turbine, and is independent of the main engine's fuel and ignition systems during the start cycle.
Plain English
A self-contained starter that burns its own fuel to spin up a turbine engine for starting, rather than using electricity or compressed air from another source.
Context Anchor
Seen in turbine-engine starting systems, aircraft maintenance manuals, and discussions of how an engine is brought up to starting speed.
Derivation
Combustion comes from the Latin 'comburere,' meaning to burn up. The name describes exactly how the unit works: it starts the engine by burning fuel inside itself, instead of relying on outside electrical or pneumatic power.
Why Pilots Care
Allows reliable engine starts when battery power or external air sources are limited or unavailable.
Grounding Statement
Picture a small fuel-burning unit making hot gas, and that gas doing the work of turning the engine for the first few seconds.
Intuition Check
Do not read “combustion starter” as meaning the engine has already started combustion normally. It means the starter itself uses combustion to create the power needed to turn the engine.
Example Sentence 1
The aircraft was equipped with a combustion starter, allowing the crew to start the engine without a ground power unit.
Example Sentence 2
In remote field operations the combustion starter provided the torque needed to bring the radial engine to life.
